Cura 'bridging' vertical holes top and bottom

Posted · Cura 'bridging' vertical holes top and bottom

Hi there,

I am having this weird issue while slicing vertical holes, I am probably missing one setting which I cannot find so I need your help
Whenever I slice vertical holes in Cura they seem to get flattened on the bottom and top making the slightly oval.
I thought it was because of the experimental bridge settings but turning them off does not make a difference. Is there a setting which enables me to print the holes as they are supposed to be printed?

Kind regards,

Knoose

    Thank you for checking it out,

    Snap, I really need the negative horizontal expansion because else it will print my holes slightly too small for all sorts of screws.
    On the other hand it already did this before I started to use horizontal expansion (but obviously less as can be seen in your second image).

    Guess I have to recalibrate my x and y axis instead of this shortcut 🙂
    Thanks again!

    Kind regards,

    Knoose

    Due to several reasons, holes are always printed smaller than designed. Using the horizontal expansion setting can compensate the dimensions for the hole, but also for all other dimensions in x/y. So, in my opinion, this is not an option, because I want to have dimensional accuracy over the whole object and not only at the holes. 

     

    Normally you have to design holes slightly larger and then they will fit your screws.

    Hello Smithy,

    Thank you for your reply, you are right of course, the few times I have designed my own items I had taken into account the offsets. Sometimes I just like to just pull stuff from thingiverse without the trouble of adapting it. Still I am aware my x and  y axis are slightly off which does not help either.

    In that case, I drill the hole after printing and you are done 🙂 

    But I know, it is not possible for every model, but normally it is easiest and quickest way.
